Bug 102590

example URL? test case? Anything?

Sometimes when I load my website ( http://zvonsully.tk ) the gif animations are stoped(frezzed),more often animations freeze when internet speed is low(when I download something).
On my webpage there are 2 animated gifs. (the spinnig "zvonsully" logo, and a picture of me on the left side)

Those gif were made in GIMP and the site contains frames and JavaScript

Can the google advertisments that i have on my site(on those frames) interact with the gifs animation?...hmmm

Does this problem still exist for you in KDE 3.5?

When I reported the bug I had a very low band internet connection. I remember that on fast coonection it didn't happend. Please check this website http://zvonsully.home.ro Because I have 2 animated gifs on the left side(menu frame) now it almost freezes Konqueror. I think is related with the bug(and the fact that my graphics drivers are the open src ones not the ati radeon from ati.com)

I just get konqueror becoming unresponsive, with 100% CPU, on that page. Seems to be something to do with the animated gif as a background image and the other animated gif on top of it. Firefox doesn't behave quite as badly, although still shows fairly high CPU usage.

> I just get konqueror becoming unresponsive, with 100% CPU, on that page. 

I see no gif stop(now are freezes. Then the animations stop and the browser remaind resposive(as the gif were not animated))
Should I open a new bug or rename this one?

My last reply was Ambiguous. I reformulate (can an admin del my prev post(#8)and this line? ):

I see no gif animations stop now. I see only freezes because of the high CPU usage.
Should I open a new bug or rename this one? 

with fixing bug #133529 this bug is too resolved

an arhive with a html file that uses gifs

the arhive contains a HTML file, a GIF file and 5 PNG files. The html file is a
picture viewer(PNG files are named 1.png , 2.png, ..., 5.png), using JavScript,
when clicking on the 2 buttons next(or previous) a png is displayed. Before a
png is displayed the image.src is set to the GIF file. So while the png is
downloading, the gif should animate. But it stops.

Usage:
-download the arhive
-extract it
-add kicker applet: Public File Server
-create a html server using these applet that points to the extracted arvive
-set the bandwidth limit to 5 kB/S
 You will have now a web server on http:// <your IP> : <selected port(8001
default)>
-open these link with Firefox and see that the gif is animated _while_ a png is
loaded
-open it with konqueror and see that while png is loading the gif stops!

see last post ; Comment #11

Results with Konqueror 3.5.5 under Kubuntu 6.06 (and Firefox 1.5.0.9) confirm the result of https://bugs.kde.org/show_bug.cgi?id=102590#c11 precisely.  I also occasionally have gifs playing once and then ceasing, but have no reproducible test-case.  In tends to happen when there are many images on a page, though.  I have not seen this behaviour with Firefox.

Uploaded zvonSully's test case here for testing: http://www.mutube.com/x/kde/bug102590/index.html

GIF-freeze reproducible on Kubuntu 6.10, KDE 3.5.5 with Konqueror cache disabled to force reloading of each image (to make delay noticeable).  Note that this is NOT a delay due to loading a new page, just the image itself. It is possible that any page with large images on will also see gif animations freezing.

I believe that the image loading should be done in a separate (with a lower priority )thread. It should sync with the main rendering every 40 ms(showing the new parts of the image that were downloaded). These image download thread should send to the main rendering the alternate text's image before the download finishes (see bug 124545 ).

another freezing GIF

if this GIF is in a html page, Konqueror will slow down

I dont know how to delete my last post. It is not for this bug ! sorry

The animations does not stop in 4.1 and 4.1.60 svn trunk 838250.

I've tested the gifs in http://zvonsully.home.ro in kde 3.5.9 and 4.1 in Opensuse 11.0 and they are always animated in both.

The testcase here http://www.mutube.com/x/kde/bug102590/index.html  I'm not sure if it works as it's supposed to (animate after the first iteration) , because the .pngs load too fast.

Could anyone else check if it still happens in recent versions?

Worksforme in KDE SC 4.4.5.
